PORTER O. HAYES, OF BURGHILL, OHIO, ASSIGNOR OF ONE-HALF TO CLINTON H.DRURY AND GLENN O. BUSHNELL, OF HARTFORD, OHIO.

ANTIRATTLER FOR THILL-COUPLINGS.

SPECIFICATION forming part of Letters Patent No. 663,884, dated December4, 1900.

Application filed February 15, 1900. Serial No. 5,341. (No model.)

T all) whom, t 71u01/ concern;

Be it known that I, PORTER O. HAYES, a citizen of the United States, anda resident of Burghill, in the county of Trumbulland State of Ohio, haveinvented certain new and useful Improvements in Antirattlers for Thill-Couplings; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart te which it appertains to make and use the same, reference being hadto-the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

Figure l of the drawings is a side elevation of the invention asapplied. Fig. 2 is a central longitudinal section of the same. Fig. 3 isa detail view of the pivot-bolt D. Fig. 4 is a detail view of thewedge-form antirattler S. Fig. 5 is a detail view of the spring K. Fig.6 is a side elevation of my invention as applied with a modified form ofspring. Fig. 7 is a detail view of the modified spring.

The invention has relation to devices for preventing thill-cou plin gsfrom rattling; and it consists in the novel construction andcombinations of parts, as hereinafter set forth.

In the accompanying drawings, the letter A designates the shackle towhich the thilliron B, having the socket C, is connected by means of apivot-bolt D, passing through the socket and bearings in the arms E ofthe shackle, which project forward from the back wall or bearing F ofthe same.

The bolt D is usually7 made with tapering ends G and perforations H,through which the ends of the vertical arms I of the spring K pass,serving to secure the bolt in place.

The perforations H may be made in the form of slots to allow forvariations in the size lof the shackle,

L represents the clamp-plate of the shackle.

S indicates the curved tapering or wedgeform antirattler, the concaveface m of which is recessed to seat the soft-rubber or leather cushionn, which is designed to engage the back of the socket or journal portionof the thill-iron O when the wedge is forced upward and forward. Theback of the wedge F of the shackle.

ing is made in the double form of a convex flange p on each side of thepart S, these lateral flanges being parallel and of equal inclinedcurvature. Forming a part of the antirattler is the transverse bar T,which is connected to the wedge portion by an extension or neck andextends laterally, forming arms V V, parallel to the ends G Gof the boltand below the same.

The spring K is usually made in one piece, consisting of a rear loopportion Z, having a downward bend at ct, and coils b of the looparmsaround the arms V V of the wedge-bar T, said coils terminating on thevertical arms I, which pass through the perforations of theshackle-bolt, as already stated.

A bent-wire bracket w or other fastening device is provided to hold theloop end of the spring in fixed relation to the rear of the shackle,this latch device giving tension to the spring and at the same timebeing easily unfastened when it is desired to take out the shackle-boltor antirattler for repair or other purposes. For this purpose the wirebracket or latch is usually made with a rearward bent loop portion toengage the rear end of the clamp-plate. When the wire latch isunfastened, the antirattler and spring can be removed in connection witheach other, leav- -ing the coupling free.

When the rear loop of the spring is forced upward to secure tension andis latched in position, the spring acts to force the wedge from theantirattler upward, while its bearing against the wall ofthe shackleforces it forward, so that it is kept in iirm and continuous engagementwith the back of the socket, holding the latter against the bolt, whichis itself held 'from turning or otherwise moving by its engagement withthe vertical arms of the spring.

It will be` noted that the convex flanges p at the rear of the wedgedecrease the friction between the wedge and shackle and lessen the workrequired of the tension-spring to force the wedge upwardly.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s

l. An antirattler for thill-couplings,having a wedge-form upper portionprovided with rear lateral convex flanges having a bearing IOOthill-iron, and having a lower portion pro- `vided with lateralextensions, and a wire spring coiled around said extensions, extendedrearwardly and latohed to .the shackle and extended upwardly throughslots or perforations of the coupling-pin, substantially as specified.

In testimony whereof I affix my signature in presence of two Witnesses.

PORTER C. HAYES.
